DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the idea of ​​this disclosure, there was a technology in which a temperature display device that displays the temperature was attached to the outer shell of the storage unit body. However, the inventors discovered a problem with the conventional technology in that humid air was likely to get in between the back side of the display surface and the device substrate, and came to form the subject of the present disclosure in order to solve this problem. Therefore, the present disclosure provides a temperature display device and a storage unit that can prevent moisture from penetrating between the display surface and the device substrate.

[0009] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially the same configurations may be omitted. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) [1-1. Configuration] [1-1-1. Storage facility configuration] FIG. 1 is a perspective view of the storehouse 1. FIG. 2 is a plan view showing the temperature display device 30 and the outer shell 20. FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2. FIG. 4 is a plan view of the outer shell 20. FIG. 4 shows the state in which the temperature display device 30 has been removed. FIG. 5 is an exploded perspective view of the temperature display device 30. The storehouse 1 of the first embodiment is an open showcase with a front opening that is installed in a store such as a convenience store or a supermarket. The main body 2 is composed of a main body 2 that opens at the front and covers the top, back, sides and bottom, and a display chamber 3. The main body 2 has thermally insulating side walls 4 and thermally insulating side panels 5 attached to both sides of the side walls 4. An inner panel 6 is provided inside the display chamber 3.

[0011] The display room 3 has a front opening 7, and inside, a pair of brackets are detachably attached to posts provided on the front side of the inner panel 6 located on the rear side of the display room 3, and shelves 8 supported by the brackets are installed in multiple stages. Products are displayed on the upper surfaces of the shelves 8. In other words, the storehouse 1 can store items.

[0012] The compressor, condenser, fan, etc. that make up the refrigeration cycle are arranged below the main body 2, and an evaporator that makes up the refrigeration system is arranged inside a cold air duct located behind the inner panel 6. By driving the compressor and fan, cold air that has exchanged heat with the evaporator rises inside the cold air duct and is discharged towards the front opening 7. The cold air discharged into the front opening 7 forms an air curtain of cold air at the front opening 7, and part of this air curtain of cold air is circulated inside the display room 3.

[0013] 1, 2, and 3, the main body 2 has an outer shell 20 and an equipment holding section 23 that holds the temperature display device 30 on the outer shell 20. The outer shell 20 is, for example, a metal panel member. In this embodiment, the outer shell 20 of the storage facility 1 functions as a cover that covers the front and top of the storage facility 1. The equipment holding section 23 holds the temperature display device 30 in a position where a display surface 35, which will be described later, is approximately flush with the outer shell 20.

[0014] The temperature display device 30 and the housing 20 will now be described with reference mainly to FIGS. The equipment holding portion 23 has an outer shell opening 21 that is provided in the outer shell 20 and into which the equipment case 32 is fitted. The outer shell opening 21 is formed as a through hole in the outer shell 20. The outer shell opening 21 is formed in a substantially rectangular shape. As shown in Figs. 3 and 4, the outer shell opening 21 has two step portions 25 formed by bending on the short sides, i.e., on two sides facing each other in the longitudinal direction. The step portions 25 may be provided on the other two facing sides of the outer shell opening 21.

[0015] Step portion 25 is formed in a step shape bent in a crank shape from the surface where outer opening 21 is located toward the inside of storage 1. Step portion 25 has engaged portion 23A that engages with device engaging portion 50 formed thereon.

[0016] The engaged portion 23A is composed of a step portion 25 and a first cutout portion 27 of the step portion 25. A temperature display device 30 is provided on the outer casing 20 of the main body 2. The orientation in which the temperature display device 30 is attached is not particularly limited, and the temperature display device 30 can be attached in any direction.

[0017] [1-1-2. Temperature display device configuration] Fig. 6 is an enlarged perspective view showing one end of the device case 32. Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 2. 5, the temperature display device 30 includes a device case 32 formed in a substantially box shape, a device board 33 housed in a case interior 32A of the device case 32, and a device lid 31 that closes a case opening 63 and a case wall portion 39 of the device case 32. The device case 32 corresponds to an example of a "case including a display surface." The display surface 35 is provided with an operation button section 35C, a display section 35D, and an operation status display section 35E. The display section 35D of the display surface 35 can display temperature, and can also display an error code. The operation status display section 35E of the display surface 35 can display information indicating the operation status of the storage 1. Furthermore, the display surface 35 can also operate the operation status of the storage 1 by the operation button section 35C, and thus the temperature display device 30 can also function as a controller. In this way, the temperature display device 30 is not limited to one that displays only temperature. In other words, the temperature display device 30 may be capable of displaying only temperature, and may have other functions like the temperature display device 30 according to this embodiment.

[0018] The device case 32 has a display surface 35 that is formed in a substantially flat shape. 2, the display surface 35 is formed in a substantially rectangular shape when viewed from the front in a plan view with the display surface 35 facing forward. The device case 32 has a substantially square frame-shaped case wall 39 extending rearward from a back surface 37 of the display surface 35. The case wall 39 has an outer shape smaller than that of the display surface 35. The back surface 37 of the display surface 35 is the surface opposite to the horizontal surface 35A of the display surface 35.

[0019] The case wall portion 39 is formed in a generally rectangular shape smaller than the display surface 35 when viewed from the front in a plan view with the display surface 35 facing forward. In the front plan view, the case wall portion 39 is formed so that the case wall portion 39 fits within the display surface 35.

[0020] The display surface 35 has a flange portion 41 extending from the display surface 35 to the periphery. Of the flange portion 41, a flange back surface portion 41A constituting the surface opposite to the display surface 35 is formed so as to extend from the periphery of the case wall portion 39 to the periphery of the display surface 35.

[0021] 3, 5, and 6, the outer peripheral surface 39A of the case wall portion 39 is formed watertight without having any through holes. Of the outer peripheral surface 39A of the case wall portion 39, a device engaging portion 50 is provided on each of two faces in the short side direction.

[0022] The device engaging portion 50 is formed in a substantially U-shape when the temperature display device 30 is viewed from the side opposite the display surface 35. With reference to Fig. 7, a gap is formed between an inner surface 50A of the device engaging portion 50 and an outer peripheral surface 39A of the case wall portion 39. As will be described later, a communication port 61 is formed inside the device engaging portion 50.

[0023] 6, in the device engagement part 50, a side part 51 formed approximately parallel to the case wall part 39 has a second cutout part 53 formed in a direction approximately perpendicular to the horizontal plane 35A on which the display surface 35 is located. The device engagement part 50 includes a movable part 55 formed by the second cutout part 53 so as to be swingable in a direction approaching the outer peripheral surface 39A of the case wall part 39.

[0024] The movable portion 55 constitutes a part of the side portion 51. The movable portion 55 includes a claw portion 57 formed to protrude away from the display surface 35, and a movable wall portion 59 provided on a side closer to the display surface 35 than the claw portion 57. That is, the device engaging portion 50 has the claw portion 57 that engages with the device holding portion 23, and the claw portion 57 and the movable wall portion 59 are integrally formed to be movable.

[0025] 6 and 7, the claw portion 57 includes an engagement portion 57A formed in the short-side direction of the temperature display device 30, and an inclined portion 57B formed so as to incline toward the center of the display surface 35 as it moves away in the vertical direction from the horizontal plane 35A on which the display surface 35 is located. The inclined portion 57B is formed so as to incline from the engagement portion 57A toward the device lid 31.

[0026] The claw portion 57 is formed so as to be detachable from the engaged portion 23A of the device holding portion 23. The claw portion 57 is also formed with a communication port 61 that communicates in a direction perpendicular to the horizontal plane 35A of the display surface 35. That is, the inside of the device engaging portion 50 communicates from the movable wall portion 59 side to the end of the movable portion 55 farther from the display surface 35, forming a space S. Furthermore, the space S communicates with a third cutout portion 70, which will be described later.

[0027] As shown in Fig. 6, the movable wall portion 59 is formed so as to protrude from the end of the second cutout portion 53 closer to the display surface 35. In other words, as shown in Fig. 7, the movable wall portion 59 is formed so as to protrude on the side closer to the display surface 35 than the flange back surface portion 41A. The movable wall portion 59 is formed on the upper part of the movable portion 55 when the display surface 35 is the upper surface.

[0028] 6 and 7, a gap 65 is formed in the claw portion 57 on a side closer to the display surface 35 of the claw portion 57. The first cutout portion 27 of the engaged portion 23A is configured so as to be insertable into the gap 65. The gap 65 is formed in the claw portion 57 at a position surrounded by the opposite side of the flange portion 41 from the display surface 35, the movable wall portion 59, and the engaging portion 57A of the claw portion 57.

[0029] 2, 6, and 7, a third cutout portion 70 facing the device engagement portion 50 is formed in the display surface 35. In addition, a third cutout portion 70 facing the movable wall portion 59 of the device engagement portion 50 is formed in the display surface 35. 7, a third cutout portion 70 is formed in the display surface 35 at a position overlapping with the device engaging portion 50 in a direction perpendicular to the horizontal plane 35A on which the display surface 35 is located. The third cutout portion 70 is formed to face the step portion 25 and to communicate with the engaged portion 23A. The third cutout portion 70 is further provided to communicate with the communication port 61.

[0030] The third cutout 70 may be formed so that the device engagement portion 50 can be accessed by inserting a tool from the outside of the outer shell 20. The third cutout 70 facing the device engagement portion 30 may also be configured so that the device engagement portion 30 cannot be seen from the third cutout. The third cutout 70 in this embodiment is formed so that the device engagement portion 30 can be seen. However, for example, the third cutout 70 may be formed so that the device engagement portion 30 cannot be seen, or may be formed with a width that makes the device engagement portion 30 invisible. Even in these cases, the device engagement portion 30 can be accessed by, for example, a tool with a bent tip or a tool having a diameter that can be inserted into the third cutout 70. As shown in FIG. 2, the third cutout portion 70 is provided only at a position where it overlaps with one of the two device engaging portions 50.

[0031] 5, 6, and 7, fourth cutout portions 71 are formed on each of two short sides of the outer periphery 35B of the display surface 35. The fourth cutout portions 71 are not formed on the horizontal surface 35A of the display surface 35, and are configured as substantially rectangular cutouts several times larger than the third cutout portions 70.

[0032] The fourth cutout portion 71 is formed on the surface of the flange portion 41 opposite the display surface 35, and the flange portion 41 at the position where the fourth cutout portion 71 is formed does not abut against the outer shell 20. The fourth cutout portion 27 is formed on the flange back surface portion 41A. By inserting, for example, a plate-shaped tool into the fourth cutout portion 71, the tool can access the device engagement portion 50.

[0033] 7, the third cutout 70 has an inclined surface 70A that inclines toward the center of the display surface 35 as it moves vertically away from the horizontal surface 35A on which the display surface 35 is located. The movable wall 59 is provided such that a corner 59A of the movable wall 59 located outside the temperature display device 30 is located inside the temperature display device 30, relative to an innermost portion 70B of the third cutout 70. In other words, the movable wall 59 is located closer to the center of the display surface 35 than the third cutout 70.

[0034] [1-1-3. Equipment board configuration] Fig. 8 is a plan view showing the device case 32 and the device board 33. Fig. 9 is a plan view showing the device board 33.

As shown in FIG. 9, the temperature display device 30 includes a device board 33 that controls the display on the display surface 35 .

[0035] First, the device board 33 will be described. As shown in FIG. 9, the device board 33 is provided with a plurality of light emitting members 81 that light up when electricity is applied. The light emitting members 81 include a first light emitting member 83 and a second light emitting member 85, which may be collectively referred to as the light emitting members 81. The device board 33 is provided with light emitting members 81 other than the first light emitting member 83, that is, the second light emitting member 85. The first light emitting members 83 are arranged in a so-called SSD (Seven Segment Display) shape, and can display Arabic numerals, alphabets, or symbols. The first light emitting members 83 are composed of a total of seven light emitting members 81.

[0036] The second light emitting member 85 is used for purposes such as representing a decimal point or an operating state of the storage facility 1. An example of the light emitting member 81 is an LED (Light Emitting Diode). The multiple light emitting members 81 are provided on the same plane of the device board 33.

[0037] 10, there are provided a light emitting member accommodating section 91 that is formed to protrude from the back surface 37 of the display surface 35 and that accommodates the light emitting member 81, and a board insertion section 97 that is formed to protrude from the back surface 37 and is inserted into the device board 33 to position the device board 33. The light emitting member accommodating section 91 and the board insertion section 97 are formed to protrude toward the device board 33 side.

[0038] The light emitting member accommodating portion 91 is configured to protrude toward the device substrate 33 and cover the periphery of the light emitting member 81. The light emitting member accommodating portion 91 has a plurality of first accommodating portions 93 that cover the total of four first light emitting members 83, respectively.

Note that the number of light emitting members 81 is one or more and can be changed as appropriate.

[0039] Furthermore, the light emitting member housing section 91 includes a second housing section 95 housing a second light emitting member 85. The second light emitting member 85 corresponds to the light emitting member 81 other than the first light emitting member 83 housed in the first housing section 93. In particular, the second housing section 95 housing the second light emitting member 85A that displays a decimal point or the like is integrally formed with the first housing section 93. The four second light emitting members 85B used to indicate the operating state of the storage facility 1 are housed in the second housing section 95 that is not integrally formed with the first housing section 93. The four second light emitting members 85B used to indicate the operating state of the storage facility 1 may be omitted as long as the temperature display device 30 is capable of displaying the temperature. The first light emitting member 83 and the second light emitting member 85A that displays a decimal point or the like constitute a display section 35D of the display surface 35 (see FIG. 2).

[0040] The board insertion portion 97 is integrally formed with the light emitting member accommodating portion 91. In particular, the board insertion portion 97 is integrally formed with the first accommodating portion 93. As shown in Fig. 10, the board insertion section 97 is formed in a cylindrical shape and is tapered toward the tip. As shown in Figs. 8 and 9, the device board 33 has an insertion hole 87 provided at a position that overlaps with the board insertion section 97 when the display surface 35 and the device board 33 are arranged. The board insertion section 97 may be formed in a substantially cylindrical shape. The substantially cylindrical shape includes, for example, a conical shape, a cylindrical shape, and the like.

[0041] The board insertion section 97 includes a first pair 97A including two board insertion sections 97 and a second pair 97B including two board insertion sections 97 spaced apart from the first pair 97A. As shown in FIG. 10, the board insertion sections 97 may be arranged asymmetrically with respect to a center line LM that divides the center of one first housing section 93 in the longitudinal direction. Alternatively, the board insertion sections 97 may be arranged asymmetrically with respect to a dividing line that passes through the center between one board insertion section 97 and the other board insertion section 97 in the short direction of the display surface 35 and extends in the longitudinal direction of the display surface 35. In this embodiment, the dividing line coincides with the center line LM. The number of board insertion parts 97 can be one or more and can be changed as appropriate. For example, the first pair 97A including two board insertion parts 97 may be configured with one board insertion part 97, and together with the second pair 97B, the temperature display device 30 may be configured with a total of three board insertion parts 97. Also, the first pair 97A and the second pair 97B may each be configured with one board insertion part 97, and the temperature display device 30 may be configured with a total of two board insertion parts 97.

[0042] The device board 33 includes a connector 89 that electrically connects the temperature display device 30 and the control unit 10 of the storage facility 1. The connector 89 is provided on the opposite side to the position of the first light-emitting member 83. Note that the connector 89 may be electrically connected directly to the drive source instead of to the control unit 10, and the position where the connector 89 is provided is not limited.

[0043] Next, the device case 32 and the device board 33 will be described with reference to Fig. 10. The device case 32 has a board receiving portion 99 formed so as to be positioned around the entire periphery of the device board 33 when the device board 33 is placed.

[0057] According to this, the board receiving portion 99 holds the entire periphery of the device board 33. Therefore, the intrusion of moisture between the display surface 35 and the device board 33 can be suppressed.

[0058] In addition, the equipment lid 31 has a lid engagement portion 113 that engages with the equipment case 32 when the equipment lid 31 blocks the case opening 63, and a board pressing portion 115 that protrudes toward the side facing the inside of the equipment case 32, and the board pressing portion 115 may abut against the equipment board 33 when the equipment lid 31 blocks the case opening 63.

[0059] According to this, the board pressing portion 115 presses the device board 33 against the board receiving portion 99. Therefore, the intrusion of moisture between the display surface 35 and the device board 33 can be suppressed.

[0060] Furthermore, the equipment lid 31 may have a lid wall portion 117 formed to protrude on the side facing the inside of the equipment case 32 and fitted into the case opening 63 of the equipment case 32 .

[0061] This closes the gap between the case opening 63 and the cover wall portion 117. This makes it possible to prevent moisture from entering between the display surface 35 and the device substrate 33.

[0062] As described above, the storage facility 1 in this embodiment comprises a main body 2 for storing items in the display room 3 (inside the storage facility), and a temperature display device 30 capable of displaying the temperature of the display room 3. The temperature display device 30 has an equipment case 32 including a display surface 35, an equipment board 33 for controlling the display on the display surface 35, and an equipment lid 31 for covering the opening 63 of the equipment case 32. The equipment case 32 has a frame-shaped case wall 39 extending toward the equipment board 33 side (rear of the display surface 35). The equipment case 32 has a board receiving portion 99 that protrudes inward from the case wall 39 and supports the equipment board, and the board receiving portion 99 is arranged around the entire circumference of the equipment board 33.

[0063] According to this, the board receiving portion 99 holds the entire periphery of the device board 33. Therefore, the intrusion of moisture between the display surface 35 and the device board 33 can be suppressed.

[0064] (Other embodiments) As described above, the above-mentioned first embodiment has been described as an example disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the above-mentioned first embodiment to create a new embodiment. Therefore, other embodiments will be exemplified below.

[0065] In the above-mentioned first embodiment, a built-in type showcase has been described in which a compressor, a condenser, a fan, etc. constituting a refrigeration cycle are arranged below the main body 2. The storage cabinet of the present disclosure is not limited to a built-in type showcase. The storage cabinet 1 may be a separate type showcase in which a compressor, a condenser, a fan, etc. constituting a refrigeration cycle are not arranged below the main body 2, and an outdoor unit in which a compressor, a condenser, a fan, etc. are provided separately from the main body 2 is provided.

[0066] In the above-mentioned first embodiment, the step portion 25 is bent inwardly in a crank shape from the surface of the outer shell 20. The step portion 25 may be any surface located more inward than the surface of the outer shell 20, and is not limited to a crank-like step shape. The step portion 25 may be attached to the back surface of the outer shell as a separate member, or the surface of the step portion 25 attached to the back surface of the outer shell 20 may be separated from the surface on which the outer shell opening 21 is located.

[0067] In the above-mentioned first embodiment, an open-type showcase is exemplified as the storage cabinet 1, but the present invention is not limited to this, and any storage cabinet capable of mounting the temperature display device 30 may be used. Examples of storage cabinets include showcases other than open-type and flat-type, refrigerators, freezers, thermostatic devices, warming cabinets, and kilns. In addition, the temperature display device 30 can be applied to general storage cabinets equipped with a temperature display device capable of displaying temperature.

[0068] (Modification) FIG. 14 is a cross-sectional view of an outer shell 200 according to a modified example. The outer opening 210 of the outer shell 200 is formed with dimensions smaller than the outer opening 21 in the first embodiment. The upper end of the device engagement portion 50 comes into contact with the back surface of the outer shell opening 210, allowing the outer shell 200 to hold the temperature display device 30. Since the temperature display device 30 has a fourth cutout portion 71, the temperature display device 30 can be removed from the outer shell 200. In this manner, the temperature display device 30 can be disposed approximately flush with the outer shell 200, or can be disposed so as to protrude from the outer shell 200.

[0069] Fig. 15 is a perspective view showing a flat storage cabinet 1000 according to a modified example. In such a flat storage cabinet 1000, the width of the outer shell 200 to which the temperature display device 30 is attached may be narrow, which may make it difficult to apply the stepped portion 25 in the first embodiment to the outer shell 200. As shown in Fig. 14, the temperature display device 30 may be attached so as to protrude from the outer shell 200. This allows the temperature display device 30 to be attached to any type of storage cabinet, improving versatility. In the first embodiment and the modified example, the outer shell openings 21, 210 formed in a rectangle have been described. The outer shell opening only needs to be able to fit the temperature display device. Therefore, the outer shell opening does not have to be rectangular. When the temperature display device is formed in an elliptical shape, the outer shell opening may also be elliptical. In this case, the outer shell opening has one step on one side and one step on the other side of any line that divides the opening in two. In addition, steps may be provided at two locations facing each other in the longitudinal direction of the elliptical outer shell opening, i.e., at two locations facing each other with respect to the major axis.

[0070] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents.
